Yes, because this section is dedicated to freshwater "Getting Started".
In respect to your situation, your new tank is still uncycled. Theres no such thing as 'cycled water' and adding the water from your established tank did nothing more than fill your new tank with water. You need to add an ammonia source to cycle it (ammonia, fish food, fish, etc). If you would like to speed this up, add some filter media from your established tank. If you plan on keeping this qt running all the time, you will need an ammonia source such as bottled ammonia to keep it cycled in between having fish in it.
Your other option is to take the filter from this new tank and run it on your established tank. In a couple of weeks, it will be established and your can transfer it to the qt when its needed for fish. The caveat here is you can not always transfer the filter back to your main tank after qt- if there is unknown disease or demise, the filter will need to be sterilized before recycling it on your main tank to prevent disease from being spread. Hope this helps!
